CP2103-EK
5. Target Board
The CP2103 Evaluation Kit includes an evaluation board with a CP2103 device pre-installed for evaluation and pre-
liminary software development. Numerous input/output (I/O) connections are provided to facilitate prototyping using
the evaluation board. Refer to Figure 3 for the locations of the various I/O connectors.
5.1. LED Headers (J5, J6)
Connectors J5 and J6 are provided to allow access to the GPIO pins on the CP2103. Place shorting blocks on J5
and J6 to connect the GPIO pins to the four green LEDs D0 - D3. These LEDs can be used to indicate active
communications through the CP2103. Table 1 shows the LED corresponding to each header position.
5.2. Universal Serial Bus (USB) Interface (J3)
A Universal Serial Bus (USB) connector (J3) is provided to facilitate connections to the USB interface on the
CP2103. See Table 2 for the USB pin definitions.
